Abstract

A refrigeration plant has a refrigerator circuit comprising a compressor (10), a condensing coil, an expansion valve (20) and an evaporator (18). Heat is absorbed in the evaporator (18) and exhausted at the condenser (14). Pressure is measured at the compressor inlet and a blower arrangement (12) for blowing cool air over a heat transfer surface of the condenser (14) is controlled in dependence upon the pressure measurement.
